From: Jonathan Nieder Date: Mon, 9 Nov 2009 15:04:41 +0000 (-0600) Subject: Retire fetch--tool helper to contrib/examples X-Git-Tag: v1.6.6-rc0~34^2~22 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=fe9a215214acd2cf9132aec70e0758786a6e3e8b;p=git.git Retire fetch--tool helper to contrib/examples When git-fetch was builtin-ized, the previous script was moved to contrib/examples. Now, it is the sole remaining user for 'git fetch--tool'. The fetch--tool code is still worth keeping around so people can try out the old git-fetch.sh, for example when investigating regressions from the builtinifaction.
